-The problem with this technique is that when each note is sounded the previous one is suddenly truncated, even though an ENVELOPE was used to give it a long release time. This happens because all the notes are played on the same **channel**, and it gives the end result a 'staccato' effect.\\ \\  To reduce this effect you can take advantage of the multiple SOUND channels available, for example the first note can be played on channel 1, the second on channel 2 etc.:\\ +</code>

-Each note is played for two 'sound periods' (normally 1/20 second each) and then allowed to decay for 4 'sound periods'; this is achieved by setting the 'hold' bit (H). To ensure that the notes are correctly 'interleaved' an initial period of silence is played on channels two and three, of 2 and 4 'sound periods' respectively.\\ \\  If you want to improve the effect even further, you can switch SOUND channel 0 from its normal 'noise' functionality to become a fourth tone channel:\\ +</code>
